WRENCH.

Application filed April 5,

This invention relates to a wrench of that type possessing a rotatableand multiple socket member.

It is an object of this invention to pro vide a novel. means forsecurely locking the rotatable socket member in its adjusted position,said means being susceptible of being readily manipulated while thewrench is in position. for operation. That is, when it is in a positionto be applied to a nut or bolt or the like.

This invention comprises the novel structure and combination of partshereinafter described and more particularly pointed out and del'ined inthe appended claims.

In the accompanying drawings which illustrate a preferred embodiment ofthis invention and in which similar reference numerals refer to similarfeatures in the dilicrent views,

On the drawings:

Figure l is an elevational view of a wrench embodying this invention.

Figure 2 is an enlarged part sectional and par; elevational view of thewrench.

lfiigure 3 is an enlarged sectional view up on the line III-III ofFigure 1.

Figure l is an elevational view of the multiple socket member.

As shown on the drawings:

In referring to the drawings it will be noted that we have illustrated awrench comprising a handle 1 having a pawl .2. The handle 1. isrotatably mounted upon a stem 3 having ratchet teeth 4 adapted to beengaged. by the pawl 2 when the handle is rotated in the properdirection. The stem 3 is bifurcated at its lower end foming a sort of'lork. In this bifurcation, the multiple socket member 5 is rotatablymounted upon a shaft 6 fastened in the wings of the bifurcation. Oneface of the socket member is in the form of a disk 5 having notches orslots 1926. Serial No. 99,709.

.7 for receiving the end 8 of a detent member 9 which is pivotedintermediate its ends upon. a pivot member 10 which bridges a suitablegap or slot 11 in a wing of the bifurcated end of the stem. A spring 12is positioned between the ope ating end of the detent 9 and the stem 3with the inner end of the spring being confined in a suitable socket 13formed in the stem.

It will be appreciatedv that when in use, the operator usually graspsthe stem 3 for adjusting the wrench on the part to be turned.Consequently it will be very convenient. to place the thumb on thedetent 9 for operating it against the spring and withdrawing the lockingend from the slot 7 in the face of the socket member allowing the latterto be rotated to bring the proper socket into position.

o are aware that many, changes may be made and numerous details ofconstruction may be varied through a wide range without departing fromthe principles of this invention, and we therefore do not purposelimiting the patent granted hereon otherwise than necessitated by theprior art.

We claim as our invention:

In a wrench, a stem having spaced wing plates, :1 member having aplurality of sockets rotatably mounted between said wing plat-es, saidmember having one of its faces provided with notches, a detent memberhaving an integral lug adapted for engaging said notches and pivotedintermediate its ends to one of said wing plates, said wine" platehaving a slot for accommodating sai detent member, and a spring fornormally maintaining said detent member in looking position.

In testimony whereof, we have hereunto subscribed our names.
